Abstract
The utility model provides a urea low-pressure deep hydrolysis waste liquor recovery device. The device comprises a hydrolysis waste liquor storage tank, wherein the inlet of the hydrolysis waste liquor storage tank is connected with a hydrolysis waste liquor discharge pipeline; the hydrolysis waste liquor storage tank is connected with a chemical feed storage tank through a pipeline and a delivery pump; the outlet of the chemical feed storage tank is connected with the hydrolysis waste liquor storage tank through a pipeline; the pipeline of the outlet of the delivery pump is provided with a waste liquor discharge port for delivering waste liquor to a gas making section; and a chemical feed port is formed on the top of the chemical feed storage tank. The urea low-pressure deep hydrolysis waste liquor recovery device is simple in structure and practical in functions, and can be used for sufficiently recovering waste water generated by low-pressure deep hydrolysis of urea production, so that the cost for discharging waste water can be reduced, gas-making desalted water consumption can be reduced, environmental pollution or equipment corrosion caused by other waste water treatments can be eliminated.
Description
Technical field
The utility model relates to a kind of urea depth of depression waste hydrolyzed liquid retrieving arrangement.
Background technology
Existing urea depth of depression waste hydrolyzed liquid or directly discharging or be recycled to the gas making utilization.And the environmental pollution that the direct discharging of waste liquid causes brings larger environmental protection pressure to enterprise, or recycle but because the low not treated direct utilization of urea production waste water PH after the depth of depression hydrolysis treatment then easily causes corrosion to equipment, affect the For Gas-making Process life of equipment.
The utility model content
The utility model provides a kind of urea depth of depression waste hydrolyzed liquid retrieving arrangement, simple in structure, safe and reliable to operation, do not increase urea and the consumption of For Gas-making Process economy, and minimizing waste water effluxes the generation expense, and reduce the consumption of gas making de-salted water, eliminate the environmental pollution that other wastewater treatment causes or cause equipment corrosion.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: urea depth of depression waste hydrolyzed liquid retrieving arrangement, comprise the waste hydrolyzed liquid storage tank, the import of waste hydrolyzed liquid storage tank is connected with the hydrolysis waste solution channel, the waste hydrolyzed liquid storage tank by pipeline be connected pump outside and be connected with the dosing storage tank, the outlet of dosing storage tank is connected with the waste hydrolyzed liquid storage tank by pipeline, is provided with at the pipeline of sending pump outlet outside waste liquid is sent to the waste liquid relief outlet that For Gas-making Process uses.
The dosing tank top is provided with dosing mouth.
Simple in structure, the practical function of the utility model, fully reclaimed the waste water that the hydrolysis of urea production depth of depression produces, reduced waste water and efflux the generation expense, and reduce the consumption of gas making de-salted water, eliminate the environmental pollution that other wastewater treatment causes, or cause equipment corrosion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, urea depth of depression waste hydrolyzed liquid retrieving arrangement, comprise waste hydrolyzed liquid storage tank 2,2 imports of waste hydrolyzed liquid storage tank are connected with hydrolysis waste solution channel 1, waste hydrolyzed liquid storage tank 2 by pipeline be connected pump 3 outside and be connected with dosing storage tank 4, the outlet of dosing storage tank 4 is connected with waste hydrolyzed liquid storage tank 2 by pipeline, is provided with at the pipeline of the outlet of sending pump 3 outside waste liquid is sent to the waste liquid relief outlet 5 that For Gas-making Process uses.Dosing storage tank 4 tops are provided with dosing mouth.
The utility model enters waste hydrolyzed liquid storage tank 2 at the waste liquor stream that the depth of depression hydrolysis produces, and after processing through dosing, delivers to the For Gas-making Process utilization after sending pump 3 pressurizations outside.Dosing storage tank 4 needs regularly to add inhibiter, and by after sending pump 3 outside and introducing waste liquids inhibiter is dissolved, the control flow utilizes potential difference automatically to flow into waste liquid and reclaims storage tank and waste liquid is carried out dosing process, and control is sent the waste liquid pH value outside and reduced corrosion.
